今天有一个挺让人意外的消息。Today there's a pretty surprising piece of news.
OpenAI宣布要关掉Sora。OpenAI announced they're shutting down Sora.
Sora就是那个AI做视频的工具。Sora is that AI tool for making videos.
你输入一句话，它就能生成一段视频。You type in a sentence, and it generates a video for you.
之前很火的。It was really popular before.
很多人都用过。A lot of people used it.
但是OpenAI说，不做了。But OpenAI said, we're done with it.
他们说，我们要跟Sora说再见了。They said, we need to say goodbye to Sora.
这个消息出来之后，很多人觉得很惊讶。After this news came out, a lot of people were shocked.
因为Sora才出来不到两年。Because Sora had only been out for less than two years.
而且当时刚出来的时候，大家都觉得特别厉害。And when it first came out, everyone thought it was really incredible.
它做出来的视频非常真实。The videos it made were extremely realistic.
有人物，有风景，有动物。There were people, scenery, and animals.
看起来就像真的一样。It looked just like the real thing.
后来他们还出了升级版。Later they released an upgraded version.
视频质量更好了。The video quality got even better.
物理效果也更真实了。The physics effects were also more realistic.
比如水怎么流，东西怎么掉下来。Like how water flows, how things fall down.
都很自然。It all looked very natural.
他们还做了手机App。They also made a phone app.
上线第一天就成了下载量最高的App。On the first day it became the most downloaded app.
所以Sora其实是一个很成功的产品。So Sora was actually a very successful product.
那为什么要关呢？So why shut it down?
最主要的原因是资源不够。The main reason is not enough resources.
做视频需要非常多的计算芯片。Making videos requires a huge amount of computing chips.
这些芯片很贵，而且很难买到。These chips are expensive, and they're hard to get.
之前OpenAI就已经限制了用户做视频的数量。Before this, OpenAI had already limited how many videos users could make.
因为芯片不够用。Because there weren't enough chips.
他们觉得，这些芯片如果用来做别的。They thought, if these chips were used for other things instead.
比如做代码、做推理、做文字生成。Like making code, doing reasoning, generating text.
这些赚的钱更多。Those things make more money.
也更有前途。And have a better future.
还有一个原因是竞争。There's another reason too, which is competition.
OpenAI现在最大的对手是Anthropic。OpenAI's biggest competitor right now is Anthropic.
Anthropic做了一个叫Claude的AI。Anthropic made an AI called Claude.
在写代码和做文字方面，表现很好。It performs really well at writing code and generating text.
很多公司和工程师都在用。A lot of companies and engineers are using it.
Anthropic的策略很简单。Anthropic's strategy is simple.
他们不做图片，不做视频。They don't make images, they don't make videos.
只专注文字和代码。They only focus on text and code.
所以他们可以把所有资源都用在最重要的地方。So they can put all their resources where it matters most.
OpenAI看到这个趋势。OpenAI saw this trend.
也决定集中力量做最赚钱的事。And also decided to focus their efforts on the most profitable things.
Sora还有一些其他的问题。Sora also had some other problems.
比如版权。Like copyright issues.
很多用户用Sora做了电影里的角色。A lot of users used Sora to make videos of movie characters.
马里奥、皮卡丘、Lara Croft这些。Like Mario, Pikachu, and Lara Croft.
这些角色是有版权的。These characters are copyrighted.
还有人用它做假视频。Some people also used it to make fake videos.
这些都给OpenAI带来了麻烦。All of this caused trouble for OpenAI.
另外，迪士尼之前投了十亿美元跟OpenAI合作。Also, Disney had previously invested one billion dollars to partner with OpenAI.
想用迪士尼的角色做视频。They wanted to use Disney characters to make videos.
但是现在Sora关了。But now Sora is shut down.
这个合作也没了。So that partnership is gone too.
迪士尼说，他们尊重这个决定。Disney said they respect this decision.
不过这十亿美元的事情。But the thing about one billion dollars.
肯定不是那么简单就算了。It's definitely not that simple to just let it go.
OpenAI现在的估值大概是七千三百亿美元。OpenAI's current valuation is about 730 billion dollars.
他们最近刚拿到了一千一百亿的融资。They just recently raised 110 billion in funding.
所以钱是有的。So they have money.
但是他们要把钱花在最值得的地方。But they need to spend money where it's most worthwhile.
做视频不是最值得的。Making videos isn't the most worthwhile.
做代码和推理才是。Making code and reasoning is.
所以Sora就这么关了。So Sora is shut down just like that.
用过Sora的人要赶紧保存自己的视频。If you've used Sora, you should hurry and save your videos.
因为以后就没了。Because they'll be gone later.
